To tl whom it 77mg/ concern:

Be it known thatI, GEORGE KLEINE, (whose post-office address is 52 State street,) a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Stereopticons; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use v the same, reference being had to the accomlongitudinally inclined,` in order that the views may be in the same horizontal plane, the degree of such inclination varying according to the distance of the curtain, and the lanterns must also be capable of lateral relative adjustment to insure the views occupying the same vertical plane.

The object of my invention is to provide a dissolving-stereopticon the lanterns composing which may be quickly and easily brought into and retained in register.

A further object of my invention is to provide a dissolving-stereopticon with simple and eiiicient means for relatively oscillating the lanterns both vertically and horizontally, whereby the views of the lanterns may be readily and accurately registered upon the same spot of an objective curtain.

The embodiment of my invention herein disclosed, generally described, consists in a dissolving-stereopticon having a pair of brackets secured to and projecting' above the slideholder of the lower lantern, a cooperating pair of brackets secured to and depending from the slide-holder of the upper lantern having horizontal slots through their lower ends, screws passing through said slots into engagement with the corresponding brackets on the lower lantern, laterally-projecting ears at each side of the frame which supports the objective lens of the lower lantern having -vertical screw -threaded holes therethrough, right and left screw-threaded rods extending through said holes, beveled gears fixed to the upper ends of said rods, a carrier comprising' I a horizontal bar above the ends of which the beveled gearsfare located, and vertical brackets in which is journ'aled a shaft having beveled gears fixed thereon in mesh with the beveled gears on the vertical rods, a disk for rotating said shaft. a screw-threaded shaftl located above the first shaft and rotatively journaled in thebrackets of the carrier, and brackets depending from the frame for supporting the lens of the upper lantern through screwthreaded holes in which said screw-threaded shaft passes.

My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and particular form, and in which- Figure 1 is a side elevational view; Fig. 2, a front elevational view; Fig. 3, a detail sectional view on line 3 3, Fig. 1; and Fig. 1, a detail sectional view.

The same reference characters are used to designate the same parts in the several figures of the drawings.

Reference characters A' and A2 designate the lamp-houses of two lanterns which are used to form a dissolving-stereopticon. B' and B2 designate the rings in which are mounted the condensing-lenses of the lanterns.

C and C2 designate the slide-holders of the respective lanterns between which and the lamp-houses the condensing-lenses are removably mounted in any desired manner-such, for instance, as by means of supporting-pins b and b2, which project from the lampe houses.

C designates a slide in which a picture is removably supported and which in turn is removably held in the holder C or C2 of the respective lanterns. c designates leaf-springs for retaining the slides within the holders.

D and D2 designate collapsible and eXtensionable bellows interposed between the slideholders and the frames D for supporting the respective objective lenses. The objective lenses are mounted in rings E and E2, each of which is in telescopic engagement with a sleeve E, fixed to and projecting from the corresponding frame D.

Any suitable means, such as indicated at e, may be provided for adjusting the objective .lenses to vary the focus.

The lower lantern is provided with supporting-feet d and (Z2 beneath the frame D, as clearly shown in Fig. 2, such feet being preferably united by a transverse rod d. Supporting-feet for the lower lanterns are also provided beneath the slide-holder,-as indicated at F in Fig. 1. y

Mounted upon the top of the slide-holder C is a pair of upwardly-projecting brackets H and H2, such brackets being preferably united at their lower' ends by a transverse strap H, through which screws pass into engagement with the top of the slide-holder. A pair of brackets G and G2 are secured to and depend from the bottom of the slide-holder U2 of the upperlantern. Thelower'endsof thebrackets G and G2 overlie the upper ends of the brackets H and H2, and are provided with horizontal slots through each of which a screw /L passes into engagement with the upper end of the corresponding bracket H' or H2. A transverse rod G preferably extends between the brackets G and G2 to give the desired strength and rigidity to the structure.

Extending across and secured to the` top of the frame D of the lower lantern is a strip O, the ends of which are provided with depending bosses 0, having vertical screw-threaded holes therethrough. Right and left screwthreaded shafts O' and O2 extend through the screw-threaded holes in the bosses 0. Beveled gears 0' and 02 are rigidly secured to the upper ends of the right and left screw-threaded rods O and O2. Located above the strip O is a carrier l), comprising' a bar, through the ends of which the upper ends of the screw-threaded rods loosely pass and above which the beveled gears are located. Brackets P and P2 extend vertically from the bar l), in which is journaled a shaft R, having fixed thereon beveled gears r and r2, in mesh with the beveled gears 0 and 02. The shaft R is extended beyond one of the beveled gears thereon and is provided with a disk 0, by means of which rotary motion may be imparted to the shaft.

Dependingfrom the frame D, which supports the objective lens of the upper lantern are two brackets S and S2, the lower ends of which are rigidly united by a cross-bar S, which lies adjacent to the upper surface of the bar l). Brackets S/ and S2 are provided with holes through which extends and in which is freely rotatable the shaft R. Alined screw-threaded holes are provided in the brackets S and S2, through which extends a screw-threaded shaft T, the ends of which are rotatively mounted in the upper ends of the brackets P and P2. The shaft T is extended beyond one of the supporting-brackets and is provided with a disk tthereon, whereby rotary motion may be imparted to the shaft.

A pair of tubes K2 extend longitudinally beneath the upper lantern and are rigidly secured within ears which project inwardly from the brackets G and G2. Rods L2 L2 are secured at corresponding ends to the frame D, which supports the objective lens. The rods L2 are in telescopic engagement with the tubes K2, by means of which the bellows D2 may be extended or contracted to vary the focus. Z designatesv a clamp-screw for locking the corresponding tubes and rods immovably together. A designates a bracket for supporting the lamp-house A2 upon the tubes K2.

rlhe bracket A is provided with collars sur` rounding the tubes and through which setscrews extend into contact with the tubes.

A saddle is adjustably mounted upon the tubes K2 for supporting the burner to which a supply-conduit N extends. m desig nates a set-screw for locking the saddle to each of the respective tubes K2.

The lower lantern is provided with similar telescopic means for uniting the frame of the objective lens to the slide-holder and for supporting the lamp-house and saddle for the burner. Ll and Kl designate telescopicallyunited rods and tubes corresponding to the rods and tubes L2 and K2, while M' designates the saddle for supporting the burner within the lamp-house A.

The manner of using and operation of my improved stereopticon are as follows: When the instrument has been so located and focused that the lower lantern will project a view upon the desired spot of a screen, the upper lantern is'adjusted as to its inclination by rotating the rod R by grasping the disk a'thereon with the thumb and linger and turning the same in the desired direction. The rotation of the rod it rotates the beveled gears fixed thereon, which in turn rotates the screw-threaded rods O and O2 through the beveled gears thereon, thereby raising or lowering the bar P with respect to the bar O across the top of the frame D. The shaft R is so rotated that the view projected by the `upper lantern occupies the same horizontal plane upon the screen as the view projected by the lower lantern.

In order that the view projected by the upper lantern may occupy the same vertical plane as that projected through the lower lantern, the screw-threaded rod T is rotated, which through the screw-threaded engagement thereof with the brackets S and S2 oscillates the upper lantern laterally with respect to the lower lantern,'such oscillation being' permitted by reason of the lateral slots g in the lower ends of the brackets G and G2, through which extend the screws it.

Itis to be understood that whileI haveillustrated my invention as applied to a dissolvingstereopticon comprising merely two lanterns, yet it is equally well adapted for stereopticons comprising more than two lanterns, it being merely necessary to interpose between each lantern and the one immediately above the same the connecting means shown and described as interposed between the two lanterns herein described.

side in the structure of the lanterns, but is adapted to be applied to a dissolving-Stereop- `ticon composed of a plurality of lanterns of any desired construction.

From the foregoing description it wil be observed that I have invented an improved dissolving-stereopticon, the views projected by the lanterns of which may be readily brought into register upon a screen and retained in register by simple and efficient means, it being merely necessary to slightly rotate one shaft to adjust the relative inclination of the lanterns and another shaft to adjust one lantern laterally with respect to the other.

While I have described more or less precisely the details of construction, Ido not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances may suggest or render expedient, without departing from the spirit of my invention.
